CVE-2026-33051

Estado: AnalizadaMedia (5.3)—

Craft CMS is a content management system (CMS). In versions 5.9.0-beta.1 through 5.9.10, the revision/draft context menu in the element editor renders the creator’s fullName as raw HTML due to the use of Template::raw() combined with Craft::t() string interpolation. A low-privileged control panel user (e.g., Author) can set their fullName to an XSS payload via the profile editor, then create an entry with two saves. If an administrator is logged in and executes a specifically crafted payload while an elevated session is active, the attacker’s account can be elevated to administrator. This issue has been fixed in version 5.9.11.

Un usuario del panel de control con privilegios bajos (por ejemplo, Autor) puede establecer su fullName a una carga útil de XSS a través del editor de perfil, luego crear una entrada con dos guardados. Si un administrador ha iniciado sesión y ejecuta una carga útil específicamente diseñada mientras una sesión elevada está activa, la cuenta del atacante puede ser elevada a administrador.
